Part 5: Common Modifications – Why Repack?

Once unpacked, you can modify the firmware. Here are the three most common reasons to repack an MXQ Pro 4K ROM.

Step 4 – Fix the Remote Control IR Mapping

  1. Locate remote.conf or sunxi-ir.kl inside /system/etc/ or /vendor/usr/keylayout/.
  2. Open your stock backup’s remote file and the repack’s file in Notepad++.
  3. Copy the entire factory_code and key_define section from your stock backup into the repack. This preserves button mapping.

5. Modifying the System Image (Debloat, Root, & Fix WiFi)

This is the heart of the repack process. We’ll modify system.img.

Step 5: Repacking the Firmware

Once you’re done modifying the mounted folder:

  1. Unmount and convert back to sparse image: Part 5: Common Modifications – Why Repack

    sudo umount super_mount
img2simg super.raw new_super.img

  2. Replace the original super.img in your unpacked firmware folder.

  3. Repack the full Rockchip image:

    afptool -pack output_folder new_update.img
rkImageMaker -rk32 new_update.img final_firmware.img

Or if using the Python tools:

./tools/afptool/afptool -pack ./output/ ./new_update.img
./tools/rkimage/rkimage make ./new_update.img ./rk3228a_modified.img

Step 4.1: Identify the Format

Run file MXQ_Pro_4K_RK3228A_20231205.img. If it returns "data," it’s likely a Rockchip packed image.

| Problem | Likely Fix | |---------|-------------| | Box won't boot after flash | Corrupted parameter.txt – restore original partition table | | Wi-Fi/BT broken | You overwrote the vendor partition with wrong drivers. Keep original /vendor/lib/modules | | Boot loop | Try flashing only super.img via fastboot: fastboot flash super new_super.img | | "Signature check failed" | Some bootloaders check hash. Disable by flashing an unlocked uboot.img from 4PDA |

Step 6.2: Repack Boot Image

Using Android Image Kitchen:

unzip AIK-Linux.zip -d boot_repack
cp boot.img boot_repack/
cd boot_repack
./unpackimg.sh boot.img

./repackimg.sh
# New image is image-new.img
